If Karla has 3 more nickels than quarters and they have a combined value of 135 cents, how many of each coin does she have?

Math, microeconomics or criminal justice
N= Q+3
5N+25Q = 135
5(Q+3) + 25Q= 135
5Q+15 +25Q = 135
30Q = 135-15 = 120
Q= 120/30 = 4
Q = 4 Quarters
N= 4+3= 7 Nickels
5(7) + 25(4) = 35+100 = 135
